Application flied Ycbruary 15, 1922. Serial No. 536,779.

To all whom it my concern:

Be it known that I, Cnmnncn B. Persons, a citizen of the United States,residing at Sweet S rings, in the county of Saline and 1 have inventedcertain new State of 'ssouri, i

and useful Improvements in Wrenches, which the following is aspecification.

This invention relates to wrenches and has for one of its objects torovide a device of this character including a handle and a detachablehead rovided with a. plurality of jaws to fit di erent sized nuts andadapted to be turned end for end on the handle to bring the various jawsone at a time into operative position.

With these and other objects in view, the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims, and in the drawingsillustrative of the preferred embodiment thereof 2-- Figure 1 is a sideelevation of the improved implement.

' 2 is a section on the line 2-2 of Fi. 1. F1 ig. 3 is a section on theline 8-3 of 4 is a perspective view of the detachable aw.

Fig. 5 is a side elevation of a modified form viewed from one side.

Fig. 6 is a. side elevation of a modified form viewed from the otherside.

7 is a section on the line 7-7 of ig. 8 is a perspective view of themodified form of jaw s own in the structure disclosed in Figs. 5 and 6.

9 is a section on the line 9-9 of e improved wrench comprises a. headmember represented as a whole at 10 and with jaws 11 of difierent sizesto fit diiferent sized nuts. The head is rovided with a longitudinallydirected soc et extending between the jaws. In Fi 1, 2, 3 and 4, thesocket is wholly within e lines of the head as indicated at 12, while inthe modified structure shown in Figs. 5 to 9, the socket is produced byan outwardly directed hood like member 13, attached to and formed in11.1 with the head 10, as illustrated. ormed within the inner face ofthe Sockployed et 12 are recesses or seats 14 in spacedrelation, whilesimilar recesses or seats 15 are formed in the inner face of the hoodmember Preferably two of the heads 10 will be emone at each end of thehandle, as

shown, to multiply the number of the jaws of difierent sizes.

The handle is represented as a whole at 16, and may be in 8 form as inFig. 1, or

straight as in Figs. 5 and 6, or other form as desired. 1

The ends of the handle are formed to closely fit in the sockets 12 orwithinthe hoods .13 as the case may be, and are provided at each endwith a longitudinally directed rccess indicated at 17 to receive aresilient holding member 18.

Each of the holding members is formed with an outwardly directed band 19to engage alternately in the seats 14 or 15 and thus form resilientcatches to yieldably lock the handle to the head.

In the structure shown in Figs. 1, 2 and 3, a keeper plate 20 isattached tothe handle 16 and extends over a portion of the longitudinalrecess 17 and one end of the latch member 13 extends beneath the kee or,while the other end of the latch mem butts against the opposite end ofthe seat 17, as shown in Figs. 2 and 3.

The keeper 20 at one end of the handle is wider than the seat 17, whileat the other end the keeper is substantially the same width as the seat.Either size may be employed as required.

The keepers 20v are sunken into the material of the handle so that theouter faces of the keepers are flush with the adjacent faces of thestock 16.

By this means the latch member is held in position by the keeper withoutother fastening means.

The latch member 18 is preferably apertured to receive a in 21 whichextends mto a recess or seat in e stock 10, as illustrated in Fig. 2, tohold the member 18 from displacement.

The extension 21 holds the member 18 in osition, and the latter requiresno other astem'ng means.

The members 17 possess sufiicient strength to hold the heads 10 fromdisplacement while to very little strain longitudinall in use, as thehandle and heads are subjfectad 0 te handle, while at the same time, t eheads can be readily detached. 'and changed end for end to present therequired size of jaw in operative I position. Theimproved implement issimple in construction, can be inexpensively manufactured of anyrequired size, is formed with few parts and is therefore. not liableto'get'out of order.

" The preferred embodimentof the invention is disclosed in thedrewingsand set 'forthin thesp'ecification, but it will be understood thatmodifications within the scope of the claimed inventidii may be made inthe construction without departing from a the principle of'the inventionorsac'rificing" any of its advantages. V

Havin thus'desoribed the invention, what is clair'ne as new is';- j I v'1 A wrench including aheadhavi g a.

plurality of nut engaging jaws and a handle a longitudinally directedhereto. 7

seated in said socket from either end, and

a yieldable catch carried by said handle and engageable with saidrecesses to yieldably lock the handle to the head.

2. A wrench including a head having a plurality of nut engaging jaws anda-handle receiving socket between the contiguous ends of the aws, saidsocket having spaced interior recesses, a handle/adapted to beseated insaid socket from eitherend and having seat in one face, a keeperattached to the handle and extending over 2a. portion of the seat, aholdin spring bearingwithin saidseat with. one en beneath said keeperand the intermediate portion bowed outwardly to project alternately intothe .recessesin the socket.
